Option 2Photovoltaic cells- this method converts the sun energy into electricity. They use photovoltaic cells which absorb the suns light. When the sunlight enters the cell, causes electrons to move, which it known as a current, this is electricity.However the energy absorbed from a single cell is very small meaning you need a lot of panels for it to be worth while.…read more

Advantages of solar1. No pollution, clean reliable energy source. Solar energy does not need to use transport to move it about.2. Long lasting solar cells, they make no noise and require little maintenance, making them cheaper.3. It will produce solar energy as long as the sun lasts, which is much longer than any fossil fuels will last.4. Easy installation, easy to install with no wires, cords or power supply's. Unlike wind power with require drilling.…read more
